AI-900 Question 95
Single answerA company wants to build an AI model to categorize incoming customer emails into predefined categories such as 'Billing', 'Technical Support', and 'General Inquiry'. Which type of machine learning problem does this scenario represent?
- A
Regression
- B
Clustering
- C
Classification
- D
Reinforcement Learning
Show answer and explanation
Correct answer: C
Explanation
This is a classification problem because the goal is to assign one of several predefined labels to each email. The labels ('Billing', 'Technical Support', 'General Inquiry') are known in advance, making classification the appropriate machine learning approach.
- A. Incorrect.
Regression is used to predict continuous numerical values, such as sales forecasts or temperature predictions. This scenario involves categorizing, not predicting numerical values.
- B. Incorrect.
Clustering is an unsupervised learning approach that groups data into clusters without predefined labels. This scenario has predefined categories, so clustering is not applicable.
- C. Correct.
Classification is the correct approach for this scenario, as it involves assigning predefined labels ('Billing', 'Technical Support', 'General Inquiry') to each email.
- D. Incorrect.
Reinforcement Learning involves training an agent to make decisions in an environment to maximize rewards. This scenario does not involve decision-making or an interactive environment.
